Pleаse chооse а questiоns from the following list to аnswer. You must answer all parts of each question, including appropriate terminology.** 5 points each A) Describe an action potential in detail. First, what is happening at the cellular level? How does an action potential travel down a neuron, and how is it transferred from one neuron to another? B) Describe homeostasis and the concepts of positive and negative feedback. How are these mechanisms used to maintain homeostasis? Give specific examples of each. C) Explain what happens when the sympathetic division of the nervous system is active. First, describe a hypothetical situation that would cause this response. Describe how your internal organs would be affected (at least 3), and which neurotransmitter is causing these effects. D) Why is it important for IV fluids to have the same concentration as body fluids? Explain what would happen to a blood cell if a patient received either pure water (0%) or salt water (3%) in an IV. E) Describe each stage of the cell cycle and explain what a cell is doing during each. F) Describe the process of protein synthesis beginning with the copying of DNA. Include an explanation of each step along with the location in the cell where it takes place. G) Explain how bones, muscles, and joints work together to perform a voluntary movement. Describe the part each structure plays in the process, using correct terminology. H) Explain the process of excitation contraction coupling. Include how a neuron stimulates a muscle fiber, and the main events within the muscle fiber to initiate contraction. I) Explain how a nervous impulse travels through the body, beginning with a sensory receptor and ending with the response of an effector. First, describe the sensation being detected, and what the specific receptor type is. Then describe the pathway of the impulse. J) Imagine that you have suffered a compound fracture of the humerus. Define compound fracture, and explain why this heightens the risk of osteomyelitis. Then explain why your fingers may feel numb and cold after your injury. K) Explain how the ABCDE rule is used to evaluate the skin for melanoma. What does each letter stand for? L) Explain the difference between ionic and covalent bonds, then give an example of a compound formed by each type of bond.
